DefaultExpressionEngineSymbols (Apache Commons Configuration 2.7 API)

java.lang.Object
- org.apache.commons.configuration2.tree.DefaultExpressionEngineSymbols

```
public final class DefaultExpressionEngineSymbols
extends Object
```
A class representing the various symbols that are supported in keys recognized by DefaultExpressionEngine.

An instance of this class is associated with each instance of DefaultExpressionEngine. It determines which concrete symbols are used to define elements like separators, attributes, etc. within a configuration key.

Instances are created using the nested Builder class. They are immutable and can be shared between arbitrary components.
